Figure 1From: In vitro cytotoxicity of Manville Code 100 glass fibers: Effect of fiber length on human alveolar macrophagesLactate dehydrogenase release from primary human alveolar macrophages (1 × 105 cells/well) following exposure to JM-100 glass fibers for 18 hours. Data are presented as percent control from 100%. Bars represent mean values ± S.E. of three independent experiments. No significant difference was found among fiber length groups of a given concentration.Back to article page
